Liebherr shows off new rugged cranes at CONEXPO

German manufacturer Liebherr has added two new rough-terrain cranes to its product portfolio, and revealed them at CONEXPO-CON/AGG in Las Vegas last week.

The rough-terrain cranes will sit in the 90-tonne and 100-tonne segments, and will be designated LRT 1090-2.1 and LRT 1100-2.1.

Liebherr says that safety was one of the main priorities when designing the new LRT cranes. As a result, they feature an outrigger monitoring system as standard.

This system allows the support status of tyres or outriggers to be detected automatically and saved to the crane controller.

The LRT 1090-2.1 and LRT 1100-2.1 cranes are also the first mobile cranes Liebherr has released which meet global safety standards and comply with all global regulations including Australian standards.

The new cranes feature Liebherr’s variable support base (VarioBase) as standard. The company says this also contributes greatly to maximising safety as it enables each outrigger beam to be extended to an optimum length.

The crane work is controlled by the load moment limiter with a Liccon controller, which calculates the maximum load capacities precisely for the current situation.

According to Liebherr, this will prevent accidents caused by human error during the assembly process and when hoisting loads.

Comfort for crane operators has also been an imperative in the design of the LRT cranes and, subsequently, cabins in the LRT range are 220mm wider than other cabins in the market. In addition, the cabin can also be tilted backwards when hoisting objects to significant heights.

Both new models feature a Cummins diesel engine which is compliant with all current US and EU emissions standards. The engine develops 194kW and makes 990Nm of torque and is mated to a six-speed powershift transmission made by Dana. Liebherr says top speed of the cranes is 25km/h.

The LRT 1090-2.1 and LRT 1100-2.1 cranes measure 3.87m tall and 3.3m wide and weigh less than 55 tonnes with equipment and ballast and less than 40 tonnes without.

The 1090-2.1 and LRT 1100-2.1 rough-terrain cranes come with a 47m telescopic boom and a 50m telescopic boom respectively.

It is yet to be confirmed if the two new Liebherr cranes will reach Australian shores.
